How to enable Alternate Company Name, BIC and Bank Branch Number at edit supplier registrations

How to add Altername Name under Company Details at Edit Supplier Registration Request UI, Its visible on Manage Supplier UI after approval but its better if we add it when we are reviewing Supplier registration Requests/Before Approval.

Same applies to BIC and Bank Branch Number under Bank Accounts section, they need to be visible at this UI as well.

Tried this using page composer but it seems these fields arent available for enablement.
